[0002]

2. Description of the Related Art In tankers and other ships, the hold provided on the hull is coated with the inner wall of the hold at the time of construction or during maintenance after construction to prevent corrosion. However, the hold of cargo carriers, especially the hold of liquid cargo carriers such as tankers (hereinafter simply referred to as “tanks”), only has a hatch on the upper deck, and the inside of the tank is mostly closed space. Even if the tank wall is condensed or the inner wall of the tank is coated, the quality of the applied coating is poor due to the temperature and humidity of the outside air.

Therefore, conventionally, in order to dry the coating in the coated tank, the dried air is forcibly sent into the tank by using a heat exchange type dehumidifier having a structure as shown in FIG. The drying of the paint on the inner wall was accelerated. FIG. 4 schematically shows a heat exchange type dehumidifier conventionally used for drying this kind of tank inner wall.

Reference numeral 02 denotes a hatch that enters and exits the tank 101.

[0004] This type of heat exchange type dehumidifier 40 is characterized by having a processing chamber 44 that takes in outside air, cools the outside air, and supplies dried air to a tank of a ship or the like. In the above-described conventional heat exchange type dehumidifier 40, the outside air is introduced into the vicinity of the processing chamber 44, and the heat in the outside air is used to dehumidify the air in the processing chamber 44. The dehumidification rotor 43 is provided between the regeneration chamber 43 and the processing chamber 44, and a heater 46 is provided in the regeneration chamber 43 to enhance the dehumidification effect in the regeneration chamber 43. It is assumed that.

That is, the regeneration chamber 43 and the processing chamber 4
4, a dehumidification rotor 42 having a cylindrical dehumidification rotor element (not shown) that rotates between the regeneration chamber 43 and the processing chamber 44 is disposed.
It is located in the regeneration chamber 43, and the lower part is located in the processing chamber 44. Between the regeneration chamber 43 and the processing chamber 44, the temperature difference and the humidity difference between the air in the two chambers are used. Is configured to cause heat exchange.

Next, the above-described conventional heat exchange type dehumidifier 40 is used.
The mechanism of the dehumidifying rotor 42 used for the above and its dehumidifying principle will be described. This type of dehumidifying rotor 42 is shown in FIG.
(A) As shown in FIG.
The dehumidifying rotor element 42a is configured such that the air in the regeneration chamber passes through the upper part, and the air in the processing chamber passes through the lower part thereof. It is configured as follows. The drive motor 42b is configured to rotate at 10 to 20 rpm.

As shown in FIGS. 5B and 5C, the dehumidifying rotor element 42a used here has, for example, a diameter of 100 mm to 4,500 mm and a width of 50 mm to 4 mm.
It has a cylindrical shape of 00 mm, and its material is made of a sheet of high-purity aluminum, etc., which is subjected to a corrosion-resistant treatment.
Corrugated (corrugated plate) 42j and liner (flat plate) 42k, which are coated by baking a moisture absorbent such as silica gel particles, are alternately laminated, and are formed in a honeycomb shape so that the surface area is increased. According to the above example, its surface area is between 2000 m2 / m3 and 30
It has a surface area of about 00m2 / m3. In addition, the hygroscopic agent 42i applied to the surfaces of the corrugation 42j and the liner 42k forming the dehumidifying rotor element 42a has an infinite number of holes of several tens of angstroms, and receives moisture in the air passing through the holes. Dry air is created.

[0008] The dehumidifying rotor element 42a configured as described above, for example, when high-temperature and normal-humidity air is blown in the upper region and passes through the honeycomb-shaped dehumidifying rotor element 42a of the dehumidifying rotor 42, the air is removed. The included heat evaporates the moisture attached to the holes of the moisture absorbent 42i on the surface of the sheet 42h. Then, the temperature of the surrounding air deprives the heat of evaporation of moisture and cools the surroundings, while the heat is stored in the sheet 42h of the dehumidifying rotor element 42a.

On the other hand, when the element 42a moves to the lower region where the air of normal temperature and normal humidity exists, the dehumidifying rotor element 42a comes into contact with the air of normal temperature and normal humidity,
Moisture (humidity) contained in the air in this region adheres to the dried hygroscopic agent 42i of the dehumidifying rotor element 42a,
That is, the heat stored in the dehumidifying rotor element 42a is dissipated, and moisture is adsorbed on the dehumidifying rotor element 42a, where the second heat exchange is performed. As described above, the dehumidification air supply can be continuously obtained by repeating the dehumidification process and the regeneration process by rotating the dehumidification rotor element 42a.

[0010]

However, in the heat exchange type dehumidifier provided with the dehumidifying rotor 42, the air from the dehumidifying rotor 42 is simply heated by the heater 46, and then cooled by using the water-cooled cooler 51. Therefore, since the efficiency is low and a large-capacity device must be used, it is often a separate device.
However, it was difficult to integrate them together. Therefore, particularly when the apparatus is moved, the dehumidifier 40 and the water-cooled cooler 51 are used.
Etc. were separately carried, and the unnecessary work of having to reassemble at the destination was forced.

A heater 46 for heating the outside air is provided.
Usually uses a power of 175 kWH, and when a water-cooled cooler 51 for cooling dry air uses a power of 46.4 kWH, a total power of 245.8 kWH is required. In order to use a large capacity dehumidifier for coating and drying in a plurality of tanks, enormous power energy was required.

The present invention has been made in view of the above-mentioned conventional circumstances. Since a sensible heat rotor is provided in a heat exchange type dehumidifying device in addition to a dehumidifying rotor, the dehumidifying device is cooled only by a cooling device. The heat of the treated air is effectively converted into the outside air heated by the heating device and used to reduce the power consumption of the heating device and cooling device, and to use small coolers and heaters that consume less power. Accordingly, an object of the present invention is to provide a heat exchange type dehumidifying device which is finished integrally and is convenient for transportation and the like.

Further, the heat exchange type dehumidifier according to claim 2 of the present application relates to the heat exchange type dehumidifier according to claim 1, wherein the latent heat exchanger rotates over the processing chamber and the regeneration chamber. Having a dehumidifying rotor element provided so that the sensible heat exchanger has a sensible heat rotor element rotatably provided over the processing chamber and the regenerating chamber. When passing the air taken in from the outside air intake of the regeneration chamber, while storing heat in the element, the element is deprived of heat,
When the temperature of the surroundings is reduced, and the portion of the sensible heat rotor element from which heat has been removed rotates and moves into the processing chamber, it removes heat from the air in the processing chamber and removes air from the processing chamber. When the dehumidifying rotor element of the latent heat exchanger passes through the processing chamber, the humidity (moisture) is absorbed by the element from the air in the processing chamber, and the surrounding area is reduced. On the other hand, when the element passes through the regeneration chamber, the temperature of the air in the regeneration chamber evaporates the moisture (moisture) adhering to the element to reduce the ambient air to low humidity.

The element 15a is formed by winding the sheet into a cylindrical shape and bonding a material excellent in adsorbing moisture in the air passing through the sheet.

Here, the situation where the sensible heat exchanger 14 and the latent heat exchanger 15 exchange heat between the processing chamber 4 and the regeneration chamber 7, respectively, will be described. First, air taken in from the outside air inlet 9 of the regeneration chamber 7 (air at room temperature and humidity, as shown in FIG.
° C, 21.23 g / kg of air)
When passing above the sensible heat rotor element 14a,
From this air, when passing through the sensible heat rotor element 14a, heat is taken from the sensible heat rotor element 14a,
The air after passing becomes high temperature air at 54 ° C. and 21.23 g / kg. On the other hand, the sensible heat rotor element 14a
In this case, the temperature is reduced by the heat deprived.
Then, the portion of the sensible heat rotor element 14a from which the heat has been deprived moves a half turn and moves into the lower processing chamber 4.

In addition, the positions of the outside air intake port, the exhaust port, the treated air inlet, and the dehumidified air outlet in the above embodiment need not be specified as long as the target air can be obtained.

Although the regeneration air passage in the other embodiment is provided in the housing to allow the regeneration air to pass through, the regeneration air passage may be provided outside the housing by a pipe or the like. Further, in the above embodiment, the dry air produced by the heat exchange type dehumidifying device was used for drying the coating in the tanker tank. However, other uses such as factories, warehouses, and archives in large-capacity buildings. May be used for dehumidification.

[0042]

As described above, according to the heat exchange type dehumidifying apparatus of the present invention, since the latent heat exchanger is provided, the humidity of the outside air is reduced, and the dried air is obtained.
The temperature of the dried air is reduced by a sensible heat exchanger, and in this dehumidification and heat exchange, the discharged air is circulated and the temperature is reused. Therefore, when the same volume of air is dehumidified, it is possible to reduce the power consumption of the heating device and the cooling device.

Further, with this configuration,
Conventional heating and cooling devices used by this type of dehumidifier can be smaller than conventional ones, and the heating and cooling devices can be integrated within the dehumidifier by arranging them inside. This makes it possible to disassemble the dehumidifying device and cooling device and move them separately when moving, compared to what was conventionally configured as a separate body, and has the effect that there is no need to reassemble at the moving destination.
